I would like to use the Print key for my own purpose. By default, it is bound to various screenshot functions.

I tried the following, which did not work: [System settings] [keyboard] [shortcuts] [screenshots]. There I disabled all Print variations with Backspace. Closing the app and reentering shows me that all these functions are disabled. What strikes me as odd is that the regular Print function is listed twice:

However, the key Print (also according to xev it's that key) still produces a screenshot.
